The principle for Day #11 on the 101-day book report says: "Lighten your load."
I moved to a smaller house about a year ago. Years of possessions had accumulated and instead of having a garage sale, I just piled up what I didn't need and gave it all away.
I think beliefs are like that, too. We pick them up from the piles that people leave out for us. But in the end, the only way they really serve us is when we let them go.
